Secondhand Smoke - Harming Hearing

We all know that smoking is unhealthy and that secondhand smoke is harmful. However, did you know it can harm your hearing? A surprising new study from the U.S. Department of Tobacco Control has concluded that nonsmokers exposed to secondhand smoke are 14 percent more likely to suffer hearing loss in the low to midfrequency range. The mechanism by which the hearing loss happens is not fully understood. Previous studies have also found an association between smoking and hearing loss.
